Real-time current
monitoring
The Monitor is RD Instruments’ most
popular direct-reading Acoustic Doppler Current Profiler.
The unit is typically bottom frame-mounted and hardwired
to shore to provide real-time monitoring of coastal
currents. The Monitor’s high data accuracy and reliability
make it a favorite for deployments in high-volume traffic
areas such as ports and harbors, where the data is often
integrated into a Vessel Traffic Monitoring System. In fact,
the Monitor has been selected for most major port programs
undertaken in the United States.
The Monitor offers a choice of three frequencies and
ranges, to meet a wide array of data requirements. The
unit also offers a flexible upgrade path, which includes an
external battery pack, pressure sensor, bottom tracking
capability for moving boat applications, and directional
wave measurement.
The Workhorse Monitor offers:
• Extreme accuracy and reliability: The
Monitor is ideally suited for the most
demanding environments, including high
traffic areas such as ports and harbors.
• Versatility: This direct reading unit can
easily be upgraded to tackle a wide variety
of coastal applications. Typical
upgrades include pressure sensor, external
battery pack, bottom tracking, and directional
wave measurement—a single
instrument can do it all!
• Precision data: RDI’s patented BroadBand
signal processing delivers very low-noise
data, resulting in unparalleled data resolution
and minimal power consumption.
• A four-beam solution: RDI’s patented
4-beam design improves data reliability
by providing a redundant data source in
the case of a blocked or damaged beam;
improves data quality by delivering an
independent measure known as error
velocity; and improves data accuracy by
reducing variance in your data.
